Heat Sink Structure

Abstract

A heat sink structure includes a heat dissipating body and at least one heat pipe. The heat dissipating body includes a main body having two opposite first and second end faces, and a plurality of radiating fins formed on two wall surfaces of the main body. The heat dissipating body is made of a heat-conducting plastic material through injection molding, and the heat pipe is embedded in the heat dissipating body during the process of injection molding the heat dissipating body. The heat pipe has two opposite first and second ends respectively exposed from the first and second end faces of the heat dissipating body for directly contacting with a heat source, and a pipe body helically extended between the first and second ends and embedded in the heat dissipating body. With these arrangements, the heat sink structure has reduced weight and material cost while providing good heat dissipating effect.
